I still think the first Halloween is a great horror movie. Very creepy.
I agree that Signs was really good/creepy up until near the end of the movie. Shyamalan's got a new movie coming soon called
The Village that looks like it's got potential to be pretty good. You can see the trailer here:

I remember seeing that same Dark Night of the Scarecrow too when I was a kid (probably on TBS too). Haven't seen it since then, but still remember how creepy it is. Looked on Amazon and it's not out on DVD and the VHS is out of print. They have some used ones for sale. I'd love to see it again.
I think Jacob's Ladder, while not exactly a horror film, was a pretty freaky movie.
